Description

Currently it doesn't support to use batch mode of the old planner via EnvironmentSettings. The following message will be thrown in that case:

: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for 'org.apache.flink.table.delegation.ExecutorFactory' in: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for 'org.apache.flink.table.delegation.ExecutorFactory' inthe classpath.
Reason: No factory supports the additional filters.
The following properties are requested:class-name=org.apache.flink.table.executor.StreamExecutorFactorystreaming-mode=false

This exception message is confusing for Python users and we should improve it.
